' Be it known that I, GEORGE L. GERALD, oi" fllqhorndike, iu lthe county of Hmnpden, und Commonrrenltli of Massachusetts, have `invented n new' and improred machine to'be 'usedfiujthe mu`.uuf`a'cture of horse aud-om" shoes, which Id'enominte n. Horse-Shoe-Celking Vilse; and Ildo hereby declare tht -the following is .a full `and exact description thereof, reference being had to the-annexed drawings, mcliing a part of'tliisspecificntion, and to the letters of referenco'murked thereon, iu'wliiclil l l. i'

' conformation, c'ell'ed'sows, are arrunged,the whole operating so that the shoe to which the cplk er eslksnrof to he applied een he grasped and held 'by the 'vise, lund. the'welding of'the collito the'body ofthe shoe, and the operations of shaping, npsetting,`n.nd nishin g, be grently facilitated by the'use ofthe steel die-plates or 'sows The construction otlmy invention isgis follows: The bese, A, and gstsnxlsrd,ll3 are ofiron, cestin one piece,` the former being made of sutlicient bottom,'ereu, and weight to n'orda solid and steady support,- and anopening,l Bf, being made through' thestundnrd to receive the leverswhich operate the jaws G; Uponythe lower end of the jcsr'C is formed the'curv'ed projection C', whichyirith the eers upon thefstandurd Band-pin10,forms n hinge, and the jaw G is thus nrranged to move tow-ord oi-.fromthe upper `part of the stimdard.V curved spring, one end of whieh'isfastenedrto the standard, -whiie .the other` beersegninst the4v jew, tends to press Vthe latter from the standard, andhold open the vise for thereception of theshoe. To close thevse, the ,heil-crunk lcser le, the fulcrum of which is thepin kl; s et in the standard, is .uttnched to the link l,-`\vl1ich moves freely cbou'tfu'pvohpessing through the ears rr, which project from the inner' side of the jaw. The bell-crank, 4lever l: is mode of snliicient thickness for thev constructionrin it oiiajrectnngulur recess or mortisne,ginto'rwhich i the ond of the link enters, und iu'vwhiohit is he1d`by arpin' passing through the sides of theinortisennd the link.,4 If the llonger crm of' the bent loyer liz-be depressed, the link l andfthe-'jarr C'rvill be d rnwutowerd the sten-derd, and thc inner edgesfot' ythesteol die-plates will hebro'ught in contoct,llike th'e'jar'rs of a. rise.A lWhen the bent llaverie released, the` curved spring will ngin'p-ress boek the jew. A.t 4the`l1 ole Ic in theV ed'of the lever 7c, I propose to attache 'chsin"o'rcd,the iowerend of which is connected'with a. foot-treadle.

j ,"Upon the upperv portV othe' jarrand ,standard rerespectirely placed the steel `die-plates or s'orvska. und 6, the peculiar conformation 'of -w'heh,us .shown -in figs. 2,8, nnd'4, is an importnpt p n'rt of my invention. "lhese' dievplates ure'ctteehed to the-ironffparts which support them .during the 'casting o f the latter, or rmly f setene'd in'properlymude soeketsf'orxuedl in the iron supports.,` The sides of theouter portionsbeing'hevelled, as shown` et t t, iig. 3, are prevented from springing upward from the seats during the powerful-hammeringto whiohthey ure subjected. The die-plates are mndethckeret the inner ends, c and d, und the upper faces of c and (Lond also of the thinner parts, are znodoplan surfaces, inwhch, however, srefforrn'ed the .recesses sind shapingdevices, which'l'will'poceed to explain. f i

Theedges of the dies srebevelled nt ejegat a. smell4 angle, the'bevel exteudiungnarlyorquite to the loner. edge of the plante..` Alongerpoz'tin `of the `edge of bis bevelled atfQso'thataoalk can'be leid in thepece' thus, chnmfered out., Jbewlled recess, j', of. about the ssmeseoton'sl erea,ybutof less length thanf, is made in thev edge of the other miie-plate, a. Y The edgeioi; a betweenthe bevelleii portions e and fis formed in the double curve h h 7L",`as shown lin igs. 2 and In the npperf'ace of a' are also made the angular recesses g g, anilin Vlike manner the angularre'cesses s s' areformerl inthe face of b, thelocation of thereeesse'sy in the surface of the die-plate beingirmaterial. It is to'be observed that the angle of inclination of the two sides of the respective recesses is dierent, and also the depth o f therecesses',.and other recesses 'may b e formed intheplate, if required for anyiparticnlar kind of work.

4The operation of my invention in reference to the most' important of tho -many uses to which it may be applied is as follows: y i Y if the shoe and calk be heated tothe proper temperature for welding, and the calk be clasped between the bevelled edges e e, "point, downward, the shoe can be applied to the base of the call: thus held, and the welding can be performed quickly, easily, and accurately. When the calks have been applied, it any of them need 4elongating or sharpening, thc bcvelled etlgef is.ns'ed, the body of the shoe Being held-between the edges of the lie-plates, while the ealk which is to be hammered lis in the bey'ellellspace'f. I I

In ,thus operating upon the two heel-calice, it is found to be convenient to use the bevelled spaceftfor one calk, and then to reverse .the shoe andapply the other calk to theopposite -bevelled space f. A small lip or projection is generally made upon the upper edge ofthe toe of a'horse shoe., and to produce this lip the shoe (having thctoe-calk weld'edupo'n it) is placed in the vise, so that the'toe-calk lies in the bevelf, and so that the curved projectionh is directly behind' the calli.' I tthe vise be drawn t'ogethm,agnd,j the-toe of .the shoe hanmnered,'lav lip will be formed, pr'ojeeting over the' end'of The angular recesses s s', q g are used-for upsetting3= the calks when the same are' found to be too long, and also operate as diesor gauges, whereby the calks on a'set of, shoes can all be made ofl uniform size and inclination.

' Iam aware'tliet bolt-heading machines forblacksmiths use have been constructed,vhaving a'standardenrl o f it, irrespective of' my arrangement and construction, but, having described my invention,

What I do-claimnsnewyand desireto secureV tay-Letters Patent, is- A (walking-vise, having -the dies a and b, with the shapingdevices hereinbefore describedA formed thereon, said'fiesa and b being'opened and closed by means of thelever'k, link l, and spring w, all constructed andoperating substantially as herein described, and for 'the purposesspeciie'd.

jan', the latter being operated by ni'enns of atreadle; and Ldo,-not.therefore claim thesaid device, or any part Y esoneri L. munitol Witnesses:
